TOWN OF ORO VALLEY
COUNCIL COMMUNICATION MEETING DATE: June 18,1998
TO: HONORABLE MAYOR & COUNCIL
FROM: David G. Hook, P.E., Town Engineer
Werner Wolff, Chief of Police
SUBJECT: Proposed Development Agreement
With Canada Hills Master Community Association
SUMMARY:
Over the years, the Oro Valley Police Department (OVPD) has received complaints from citizens of
the Canada Hills community regarding traffic violations occurring within the various
neighborhoods. Because the streets are `private', not `public', the OVPD has been unable to enforce
state and local traffic laws in these neighborhoods with the exception of reckless driving and drunk
driving. As a result of the complaints, the OVPD and the Canada Hills Community Association
(Association) have researched the nature of the complaints and found that the most numerous
problem appears to be speeding. In some areas, it has been confirmed that the 25 MPH speed limit is
consistently ignored by the motoring public, with the average speed at approximately 30 MPH and
the 85`h percentile at approximately 35 MPH.
Recently, the state legislature has passed a law, codified as ARS Section 9-500.05, that would permit
the Town to enter into a Development Agreement for the purposes of enforcing traffic laws. Town
staff has been approached by agents of the Association regarding the possibility of the Town and the
Association entering into such an agreement. Town staff and the Association's agents have discussed
the issues on several occasions. Tobin Sidles, Town Attorney, has drafted the attached draft
Development Agreement (Agreement) based on those conversations.
The essence of the Agreement is as follows:
➢ Regarding the Town:
• OVPD will patrol the private streets that are not gated.
• OVPD will provide traffic/emergency vehicle enforcement on the private streets that are not
gated.
• The DPW will evaluate and advise the Town Council on the appropriate traffic issues and
regulations.
• The Town Council will, upon the advise of the DPW, enact regulations for the OVPD to
enforce.
• The DPW will install the appropriate traffic control (signage, striping and painting) necessary
for the regulations enacted by the Town Council.
• The DPW will invoice the Association for the costs (labor, material and equipment) for the
traffic control measures referenced above.
• The Town will not be responsible for street maintenance of the private streets.

COUNCIL COMMUNICATION PAGE 2 OF 2
➢ Regarding the Association:
• The Association grants the Town permission to do the above referenced evaluation,
enactment, installation and enforcement.
• The Association will reimburse the Town for the costs of DPW's traffic control measures.
• The Association indemnifies the Town for all liability for the actions of the town when
implementing the agreement.
➢ General:
• Streets that are currently `private' can become `public' streets if the provisions of the Town
Code regarding doing so are followed.
• If any streets that are currently `private' become `public', the agreement will not apply to
those streets.
• The Agreement is for a one year period, automatically renewed upon the adoption of the new
FY budget, unless canceled by either the Town and the Association with 90 days notice
• The agreement does not change densities and uses from the status quo.
• Future rezonings will be considered in light of the policies in force at the time of the
rezoning.
ATTACHMENTS: Draft Development Agreement
FISCAL IMPACT:
The fiscal impact to the DPW would be a net of zero since the costs of signage, striping and painting
would be reimbursed to the Town by the Association.
RECOMMENDATIONS OF STAFF:
The staff of both the OVPD and the DPW support the favorable consideration of the Development
Agreement as presented.
SUGGESTED MOTION: None required. e-

TOWN OF ORO VALLEY
COUNCIL COMMUNICATION MEETING DATE: June 18, 1998
TO: HONORABLE MAYOR & COUNCIL
FROM: Shirley Seng
Utility Administrator
SUBJECT: Water Utility Commission 1998 Annual Report
SUMMARY:
The Oro Valley Water Utility Commission (Commission) was established in 1996. The
Commission's function is to act as an official advisory body to the Town Council on the utility's
capital improvements program planning and rate structure formulation. Pursuant to the Water
Code, the Commission must render its Annual Report to the Town Council with their
recommendations for the upcoming year.
The 1998 Annual Report contains recommendations for fiscal year 1998/99 on the following
topics:
• Water Rates
• Financial Criteria
• Department Structure
• Alternative Water Resources
• Master Planning Reports
• Oro Valley Water Improvement District#1
• Tucson Water system within Oro Valley
A copy of the Executive Summary has been attached for quick reference. Greater detail on each
recommendation is presented in the body of the Annual Report.
In preparation of the Annual Report, the Commission's finance subcommittee spent
considerable time analyzing financial scenarios prepared by a rate consultant, Mr. Ron
Kozoman. Mr. Kozoman will be present at the study session to explain and answer questions
pertaining to the proposed rate structures. The Annual Report contains a "Preferred Financial
Scenario" that would increase revenue by 5.50% for fiscal year 98/99. This would be
accomplished by increasing the typical residential customer's base rate by 10 cents, increasing the
commodity rate by 2 cents per 1,000 gallons and decreasing the amount of water included in the
base rate from 2,000 gallons to 1,000 gallons. The Town Manager has proposed a different
financial scenario that would provide for a 4.60% increase in both the base rate and the
commodity rate leaving the amount of water included in the base rate at 2,000 gallons. Staff's
review of the Town Manager's proposal indicates that it meets the same financial criteria as the
"Preferred Financial Scenario" recommended in the Annual Report. Tables for both financial
scenarios have been attached for quick reference.

EXECUTIVE SUMMARY
TOWN OF ORO VALLEY
WATER UTILITY COMMISSION
ANNUAL REPORT
APRIL 1998
INTRODUCTION
In October, 1996 the Oro Valley Town Council (Council) formed the Oro Valley Water Utility
Commission (Commission) to act as the official advisory body to the Council regarding water
related issues. The functions and duties of the seven member commission include reviewing
and developing recommendations for water revenue requirements, water rate and fee structures,
and water system capital improvement planning. The Commission is required to prepare an
annual report to the Council regarding its recommendations. This report is the Commission's
second Annual Report. It includes recommendations related to financial criteria, revenue
requirements, system operations and maintenance requirements, debt service requirements, a
five year capital improvements plan, possible rate adjustments, alternative water supply options,
system expansion and future organizational structures.
This Executive Summary contains a briefing on the implementation of the recommendations
presented in the 1997 Annual Report. It also contains a briefing on new recommendations
specific to water issues facing the Town in FY 1998/99. Explanations and financial analyses
that are more detailed may be found in the body of the report. The main body of the report
presents details related to the Commission's preferred scenario. For comparison purposes, a
section describing other alternatives is presented at the end of the report.
IMPLEMENTATION OF THE 1997 REPORT RECOMMENDATIONS
• Water Rates: A 3% across the board rate increase for all customer classes was
recommended by the Commission to the Town Council. The Town Council implemented
an adjustment to the minimum monthly rates and the commodity rate for the customers of
the Rancho Vistoso system, equalizing all rates for customers in both systems, except for the
`city' customers whose rates were adjusted with the phase-in formula established by Council
at the time of purchasing the two former private utilities.
• Consolidation of Water Operations: The Commission recommended that the operations
of both systems (CH & RV)be consolidated to take advantage of economies of scale in both
- 1 -
field operations and administration. The Town Council approved a consolidated budget for
p
the FY 1997/98. The two billing systems have been consolidated and a new full-page bill
format with return envelopes has been implemented. The physical interconnects are
scheduled to begin this fiscal year and will be completed in FY 98/99.
• Rancho Vistoso Depreciation Expense: The Commission recommended that the Town
update and perform long range financial projections to ensure the timely recovery of
depreciation and continued system reliability and capacity. Those projections are
incorporated into the 1998 Annual Report and allow for the full recovery of depreciation for
the entire system.
• Alternative Water Resources: The Commission presented three recommendations to the
Town Council involving alternative water issues: (1) Phased in use of reclaimed water to
irrigate golf courses; (2) continue joint planning with neighboring jurisdictions and other
water agencies; and (3) purchase incentive priced CAP water. Efforts to address all three
have begun and continued during the year.
• Master Planning Reports: The Commission recommended that the Master Planning
Reports be updated. A proposal from a consultant has been received and is under evaluation
by staff.
NEW RECOMMENDATIONS FOR FY 1998/99
• Water Rates: The Commission recommends a 5.50%revenue increase for FY 98/99. The
proposed revenue increase would allow the utility enterprise fund to meet sound financial
criteria regarding the operations of a municipal utility while costs keep pace with inflation,
growth issues are not ignored, infrastructure is replaced as it is worn out and the level of
service to the customer improves.
The manner in which this revenue increase is proposed to be accomplished includes the
following changes for all residential and commercial customers:
> The change in the monthly base rate is recommended to increase between $0.10/month
and $148/month, depending on the meter size. Most residential customers have a
5/8"X3/4" meter. These customers would realize a $0.10/month change in their monthly
billing under this proposal.
> The number of gallons included in the base rate is proposed to change to 1000 gallons
from 2000 gallons for all customers.
> The commodity rate for all customers is recommended to increase $0.02/1000 gallons.
More detailed discussion on water rate recommendations are included in the main body of
the report and in Appendix D, including residential and commercial customers as well as
`city' and `non-city' customers.
- 2 -
• Financial Criteria: The Commission recommends that the Town Council adopt the
following criteria as policy to guide staff in operating the utility using sound business
practices that protect the long term interests of the rate payers:
➢ Retained earnings shall never become negative.
➢ The utility shall not operate at a net loss on the income statement for more than two
consecutive years.
➢ Cash flow shall be sufficient to pay personnel, O&M and debt service.
➢ Cash reserves for operation shall not normally be less than 15% of the expected cash
outlays, excluding capital. Cash reserves may fall below this threshold, but not for more
than 2 consecutive years.
➢ Debt service coverage shall not be less than 1.25 times the annual debt service as
required in the bond covenants.
➢ Depreciation shall be fully recovered through rates each year for reinvestment in the
system,to be verified through an analysis of expected plant life every five years.
➢ In the case of unforeseen circumstances, every effort shall be made to avoid borrowing
funds. Instead, deferment of other expenses and use of cash reserves should first be
explored before consideration of incurring debt.
• Departmental Structure: The Commission recommends that the water utility be
established as a separate department. As Oro Valley continues to grow, the separation of the
water utility from the Department of Public Works is inevitable. Combined with the unique
nature of operating a municipal water utility within the Tucson Active Management Area,
there is a need for staff to focus resources on strategic and tactical issues. A separate
departmental structure could be more effective in answering the utility's ability to fully
participate in regulatory and regional water issues and to provide improved overall service to
customers.
• Alternative Water Resources: Given the importance to the residents of Oro Valley of
addressing alternative water resource issues and the progress made in the last year, the
Commission recommends that efforts on the same three points presented in the 1997 Annual
Report be continued. To reiterate the three points, they are (1) the phased in use of
reclaimed water to irrigate golf courses, (2) the Town continue joint alternative water
resource planning with neighboring jurisdictions and other water resource agencies to take
advantage of economies of scale; and (3) purchase incentive priced CAP water while it is
available for accumulating long term storage credits.
• Master Planning Reports: The Commission recommends that the Town create two
separate Master Plan Reports. One report would be for the domestic water system,
consolidating the two Master Planning Reports currently in place. The new second report
would be for alternative water systems, which currently have no master plan in place.
• Oro Valley Water Improvement District #1: The Commission recommends that the
Council provide proper notice to the Metropolitan Domestic Water Improvement District
and incorporate the management of the production and delivery systems within OV #1 into
- 3 -
the new Utility Department if the Task Force established to study the issue determines that it
would be in the best interests of the Town and OV#1 customers to manage that system.
• Tucson Water system within Oro Valley: The Commission recommends that the Town
Council pursue an analysis of the acquisition of the delivery and production system currently
serving residents of the Town who are customers of Tucson Water.
The Oro Valley Water Utility Commission is proud to serve the Council and customers of the
Town of Oro Valley. We are pleased to present our Annual Report to the Town Council for
consideration. While much has been accomplished in the past year, the Commission looks
forward to direction from Council regarding those items mentioned in the Executive Summary
and detailed in the Report. We thank the Council for their consideration, direction and guidance.

Town of Oro Valley Council
Oro Valley Water Utility
Goals Of Rate Setting
Rates should be set that recover all costs and meet debt service requirements. (Debt
service is computed as net income plus depreciation divided by interest and principal
payments.)
Rates should be cost based, that it, the customer causing costs should pay his or her
costs via rates charged. Determining whether or not the customer is paying his or her
costs is done via a cost of service study. A cost of service study allocates expenses and
assets (and the return on the assets, and recovery of the assets via depreciation)to each
customer class. The revenues are then compared to the expenses, and the investment to
produce the revenues, to determine if the customer is paying his or her cost of service.
In the ideal world, all customers would pay exactly the cost to serve them. However, in
the real world this rarely occurs. But, rates should be set as close as possible to costs.
Rate increases should be as gradual as possible, to avoid rate shock to customers.
Frequent small rate increases are preferable to a"one-time catch-up"rate increase.
Rates should be easy to understand by the customer, so that they can control their bill.
The monthly minimum charged customers should recover the cost of reading the meter,
billing and collection costs. The monthly minimum should provide for a return on the
investment in meters and service lines, office equipment, and other customer equipment
to enable the utility to pay the interest cost associated with these assets. Finally, the rates
must provide for depreciation on meters, service lines, office equipment, and other
customer equipment to (1)provide funds for replacement of these assets, and (2) provide
for repayment of debt incurred to purchase the assets. These costs are called "customer
costs".
The customer costs continue even when the customer uses no water, as the investment in
meters and service lines continues to depreciate, and the interest and principal payments
must still be made.
1
The commodity rate, or the rates based on the amount of water used, should recover the
cost to provide the water, or all other costs other than customer costs.
Please turn to Tab 2
The current rates charged customers result in some classes of customers being subsidized
by other classes of customers. The attached cost of service study is based on the actual
revenues, expenses, and plant for the twelve months ended November 30, 1997. The rate
return at present rates is shown on Schedule 1, line 21. The rate increase needed to
achieve a uniform rate of return is shown on Schedule 2, line 18. As can be observed
from this schedule, if the goal was to derive a uniform rate of return from each customer
class, substantial increases and decreases would be needed. A uniform rate of return
would required a rate increase of approximately 24% for customers on 5/8"x 3/4"meters,
and a rate decrease of approximately 69% of customers on 6" meters. (These data are
summarized on page 3 of the text.) The computed monthly minimums and the
commodity rates are shown on Schedule 2, pages 3 and 4. The only way to achieve a
uniform rate of return would be to have different commodity rates for each class of
customer(meter size).
A summary of the cost of service study based on meter size shows the following as to
number of customers, gallons sold, earned rate of return at present rates, and rate increase
needed for a uniform rate of return based on the revenues and expenses for the twelve
months ended November 20, 1997 (numbers in(parentheses) indicate negative numbers):

Water Included In The Monthly Minimums Charged Customers
The customer views this water as "free water". However, there is no free water, as the
monthly minimum must recover the cost of this water.
Arizona Department of Water Resources considers a high amount of water included in the
monthly minimum as non-conservation measures.
Inclusion of water in the monthly minimum does help to "justify"the monthly minimum
to the customer.
However, educating the customer on why he or she is paying a monthly minimum bill is
preferable to including water in the monthly minimum.
Rates Charged Customers Serve Many Purposes
Rates charged customer provide the necessary revenues for the water utility to provide
service and install plant as needed to provide quality service to customers.
Rates provide a message to customers relating to the costs incurred to serve that
customer.
Rate can act as a conservation measure.
The Major Variables In Setting Rates For A Water Utility
Projected and estimated expenses must be included in the rates charged customers. The
utility cannot charge retroactive rates to make-up for expenses incurred, but not recovered
from customers. Thus, every attempt must be made to determine what future plant
additions will be needed, and what level of revenues (customer additions) and expenses
will be incurred.
The amount of plant to be installed and when it will be installed impacts the need for
higher rates charged customers (to provide cash flow), the need for a higher hook-up fee
or impact fee, and/or borrowing to install plant. At this date, rates cannot pay for the
plant to be installed in the near future. Additionally, increased rates will still not be
sufficient to pay for the new plant needed.
Assumptions regarding customer additions has a major impact on(1)plant to be installed,
(2) expenses in the future, and (3) future revenue.
The current estimate for customer additions is 780 new customers per year. If the number
of new customers is higher or lower than the estimated 780, the need for plant and the
level of expenses and revenues will change.
4
A shortfall in customer additions will have a substantial impact on the water utility's net
income.
The CAP water and recharge costs continue to increase, substantially impacting net
income. The costs associated with the CAP water and the recharge will be approximately
$176,961 in fiscal year 1998-99. By fiscal year 2002-03,these costs are estimated to be
$314,328.
Plant Additions And The Hook-Up Or Impact Fee
The utility should have as much storage capacity as financially possible, so that it will not
be forced into pumping during the daytime, when electric rates after de-regulation may be
higher due to pumping during peak periods. Peak periods could be from 7 AM to 7 PM.
Increasing the hook-up fee or impact fee will decrease the need to borrow in the future.
Hook-up fees or impact fees are a source of cash, but do not impact the net income, nor
debt service coverage.
When The Golf Courses Leave The Groundwater System,
There Will Be A Substantial Impact On Utility's Net Income And Cash Flow
When the golf courses leave the system, there will be a major impact on revenues and
minor impact on expenses.
The expenses that will not be incurred consist of meter reading, billing and collection,
and power costs. The power cost is approximately $0.26087 per 1,000 gallons of water
sold. Golf courses, with the exception of the Vistoso course, are paying $1.71 per 1,000
gallons, which has a substantial impact on net income, as the incremental revenues
exceeds the incremental expenses of serving this customer.
Please turn to Tab 3
The Vistoso, Sun City, Canada Upper and Lower Golf courses generated $847,141 of
revenue in the twelve months ended November 30, 1997. These revenues represented
approximately 26.60% of revenues from water sales.
Note on page 1, that the operating and maintenance expenses represent approximately
35.90% of total revenues, while depreciation expense represents approximately 23.50%
and interest expense represents approximately 29.40% of revenues.
5
Oro Valley Water Utility compares to the companies followed by the National
Association of Water Companies ("NAWC"), in the 1996 Financial Summary for
Investor-Owned Water Utilities, Economic Research Program as follows:
Expenses as a Percent of Revenues
NAWC Oro Valley
Operating and maintenance expense 50.10% 35.92%
Depreciation expense 9.55% 23.48%
Tax expense 17.60%
Interest expense is not aggregated,thus no comparison is available for interest
expense.
The income lost from water sales to golf courses must be reallocated to all other customer
classes. The reallocation will result in all other classes of customers rates being increased
substantially. Please note that net revenues or net income from the golf courses totaled
$689,863 while the total net income of the water utility was only $500,945 for the twelve
months ended November 30, 1997. Please see page 2 of the above schedule.
Possible Changes In Rates Charged Customers
To make it easier to gage the impact of an increase in the monthly minimums or the
commodity rates, I have prepared the following schedules.
Please Turn to Tab 4
A $0.10 increase in the monthly minimums charged customers results in an increase in
revenues of $18,677. The $0.10 in monthly minimums is higher for larger meters. The
increase to larger customer is based on potential water flow through the meter, or the
demand a meter can put on the system. A 5/8 x 3/4 inch meter can flow 20 gallons per
minute, while a 1 inch meter can flow 100 gallons per minute. Thus the increase to a 1
inch meter would be $0.50 ($0.10 x(100 /20 gallons per minute)). The higher increase
to the larger meters is due to the demand that a larger meter can place on the system.
The monthly minimums for each meter size are shown on Schedule A, Page 3. The
$18,677 includes revenues from customers using revenue annualization methods to year
end customer levels at present rates to June 30, 1997, and revenues from 780 new
customers to June 30, 1998.
Because of the three year phase-in rate increases to "City Customers" increasing the
monthly minimums by $0.20 will not produce exactly $37,354.
6
A $0.01 increase in commodity rates results in $22,772 in additional revenues. These
schedules are labeled as "B".
Possible Rate Increase Scenarios
(Please be advised that no conservation or weather impacts have be
included the in the following rate increase scenarios. Southern Arizona
experienced less than normal rainfall during the years 1994-97.)
The following schedules result in increases to customers in the amount of approximately
$234,766, the rate increase being recommended by the Water Utility Commission.
Please refer to Tab 5
This scenario includes an increase of$0.34 in monthly minimums, no increase in the
commodity rates, and the 2,000 gallons included in the monthly minimum to all
customers is reduced to 1,000 gallons. These schedules are labeled as Schedule 1. The
increases rate from this proposal are $234,549.
The advantage of this rate design is that conservation efforts are being made via the
reduction of water in the monthly minimum. Additionally the future loss of the golf
course revenues are starting to be transferred to all customers. Finally, the increase in the
monthly minimum adds stability to the water utility's revenues and resulting net income.
Please refer to Tab 6
This scenario includes no increase in monthly minimums, an increase in the commodity
rate of$0.024314, or $0.02 or $0.03, and the 2,000 gallons included in the monthly
minimum to all customers is reduced to 1,000 gallons. These schedules are labeled as
Schedule 2.
The increased rates from the scenario with an increase in the commodity rate increase of
$0.024314 are $234,769. Unless fractions of a cent are used for the commodity rates,the
resulting rate increase either exceeds or produces a shortfall from the Water Utility
Commission rate increase recommendation.
The increased rates from the scenario with an increase in the commodity rate increase of
$0.02 are $226,945.
The increased rates from the scenario with an increase in the commodity rate increase of
$0.03 are $245,081.
The advantage of this rate design is that conservation efforts are being made via the
reduction in the gallons in the monthly minimums, and the increase in the commodity
rate. Additionally the future loss of the golf course revenues are starting to be transferred
to all customers.
However, an increase in commodity rates means that more revenues from golf courses
will have to be transferred in the future to all other classes.
Please refer to Tab 7
This scenario only includes a$1.77 increase in monthly minimums. There is no increase
in the commodity rate, or change in gallons included in the monthly minimum.
The increased rates from the scenario with an increase in the monthly minimum total
$234,293.
The advantage of this rate design is that the future loss of the golf course revenues are
starting to be transferred to all other customers. Additionally revenue stability has been
increased via the increase in the monthly minimums. These schedules are labeled as
Schedule 3.
Please refer to Tab 8
This scenario includes an increase of approximately 6.00% in the monthly minimums,
and a 5.26% increase in the commodity rates. This would be an across the board (all
customers) rate increase. These schedules are labeled as Schedule 4. The rate increase
would be $235,329. Using whole cents for the commodity rate make it impossible to
exactly match the Water Utility Commission's recommended rate increase.
This scenario does produce some conservation effort. The increases in the monthly
minimums increase revenue stability. However, an increase in commodity rates means
that more revenues from golf courses will have to be transferred in the future to all other
classes.
Thank you for your time and patience.
